摘要
任意反射面的速度干涉仪(V ISAR)用来测量极高速运动的物体,但是由于探测仪器响应速度的限制,使探测仪器在被测目标开始运动的瞬间,无法分辨出移过的条纹数,导致整数条条纹的丢失。解决条纹丢失问题有多种方法,其中使用双灵敏度V ISAR是一种有效方法。通常双灵敏度测试系统都使用两套独立的速度干涉仪和探测仪器,这使得装置庞大并且昂贵,同时又增加安装、调试和维护的难度。提出一种双灵敏度测试系统,只使用一套速度干涉仪和探测仪器,即单速度干涉仪上的双灵敏度系统(DSSV I)。
Velocity interferometer system for any reflector (VISAR) is an effective tool to measure high-speed motion objects. However, because of the limitation of response speed of the detector, it is unable to resolve the number of shifting fringes in a very short time at the beginning of motion of the object, which lead to a question of fringe lost. The double-sensitivity VISAR is one of ways to solve the question. In this article, we advance an improved double-sensitivity VISAR that only uses a set of velocity interferometer and detection system. It is double-sensitivity system in single velocity interferometer (DSSVI).
